Davos forum hits turbulence over CEOs' private jets

Touting its green credentials, the World Economic Forum has pushed back against research that said company bosses are flying to Davos in record numbers on polluting private jets. The study this week from the leasing company Air Charter Service (ACS) forecast that nearly 1,500 such flights would occur over the week of the forum, to and from four airports near Davos in the Swiss Alps.
